Readmissions to a Surgical Intensive Care Unit: Incidence and Risk Stratification for Personalized Patient Care.

Unplanned readmission to the surgical intensive care unit occurred in 6.4% of patients and was independently associated with age, malignancy, and delirium.

Readmission was strongly linked to prolonged hospitalization and increased short- and long-term mortality. Early recognition of high-risk patients and targeted, personalized preventive strategies may help reduce avoidable readmissions.
